AI Technical Summary

Benefits of technology

[0059] Thus, there is provided an assistant apparatus attached to the user apparatus which allows an assistant to monitor the process of the user and to instruct the user in the process.

Problems solved by technology

It has been determined that movement of the user's head into the diagnostic Hallpike positions and through the relief head positions sequences of the Epley maneuver is a complex maneuver.
The times during which the goggle device will be used is further complicated by the user being dizzy with the associated loss of orientation in space.

case 1

[0757] 45 degrees

[0758] With the constants Tos and RySCALE, there can be calculated an angle for a dwell time. A 45 degrees rotation is depicted in FIGS. 234A, 234B. Note that T0-T1 time exceeds the T0-Tos time, so it is known that the angle is between 0 and 90 degrees. At 45 degrees, the output will be sin(45).times.RySCALE.

[0759] First it is found out what the sensor would produce at 45 degrees

Ry Count=RyOFFSET+sin(RotAngle).times.RySCALE

Ry Count=2500+0.707.times.625

Ry Count=2942

[0760] This is the count that will be received from the sensor for Ry at 45 degrees.

[0761] To convert this number into an angle, first remove the offset:

Ry=Ry-ROFFSET

Ry=2942-2500=442

[0762] Next the number is scaled to get a sine

sin(RyAngle)=442.times.0.016=0.707

[0763] To find the Rotation angle, take the arcsine

ROT=arcsine(0.707)=45 degrees

case 2

[0764] 325 (-25 degrees)

[0765] At 335 degrees, the sensor will output

Ry Count=RyOFFSET+sin(ROT Angle).times.RySCALE

Ry Count=2500+(-0.4226).times.625=2500-264=2236 counts

[0766] Given this count from Ry, the angle can be found the by

Ry=Ry-RyOFFSET

Ry=2236-2500=-264

[0767] Scaling

Ry=-2640.0016=-0.4224

[0768] Finding the Angle

Ry=arcsine(-0.4224)=24.98.degree.

[0769] Transposing to the Reference Frame (FIG. 191 Math Model)

Ry=360-25=335.degree.

[0770] Control Flow

[0771] Refer to FIGS. 193-200 for the flow charts describing the software operations. Starting with RESET at 821 in FIG. 193, the flow initializes the system at 822 then goes into a continuous loop beginning at operation 823 consisting of reading the switches and sensors, determining what procedure to follow, calculating the angles and optimizing the choice of which vector to use. At 824-827 switches S2-S5 (See FIG. 189C) are scanned to determine which procedure to follow. Initialization at 822 includes Clear Counters. Reset Router, ...

[0806] To Diagnose Right Posterior Semicircular Canal BPPV.

[0807] The user is instructed to sit on the floor and / or mat as shown in FIG. 206A and put the goggles 921 over his eyes in such a manner that the LED screen is clearly seen.

[0808] The User is Instructed to Lie Supine in Position "R", FIG. 205A.

[0809] The pillow is rolled lengthwise and used longitudinally under the spine from C5 to L1. The user is instructed to place the pillow on the mat behind him such that the pillow will be positioned under his upper thoracic spine (not under his shoulders). He is then instructed to push the center button S3 of the four goggle buttons. He is instructed to follow the head direction indicated by the LED arrows 206B. The up D1 and right D5 arrows will blink and the user will lie backward upon the pillow and floor. The user is to extend his neck until the up arrow D1 ceases fla...

Abstract

The apparatus includes a fluid suspended, inner member, which has printed upon it a series of position bull's eyes, which are connected by a path printed on the inner member. The inner member is contained within a transparent, watertight outer housing, which has a sighting marking printed upon it. The device is attached to the user's head in a manner such that when the user moves his head, the outer member can move relative to the inner member. This allows the user to follow the path to visually track his correct head position through the posterior canalith repositioning maneuver sequence. Also attached to the user apparatus is an assistant apparatus which includes a hollow ball containing a liquid sufficient to form a small bubble which allows an assistant to follow a second path which corresponds to that seen by the user when he follows the user path.
